Title: Maybe a Screw up
Post by: Daniel Penney on May 11, 2019, 12:28:42 PM
So I did something stupid. I put my yeast in freezer. Ya I know. I took it out and had it in fridge weeks before I used it. I pitched it Sunday. Wel Mo/Tu no activity. Wednesday rolls around and she’s going good. Still to this day.  I’ve got a another yeast I could pitch in. Should I?  Or do yall think I’m fine?

Likely will end up OK. 48 hour lag phase is a little long but it sounds like the yeast have adapted to the environment and should be able to do their job.  Just watch and see what happens for now.

Liquid or dry yeast?

Dry wouldn't have been affected,  but freezing the liquid yeast probably noticably reduced the number of viable cells.  So you you had a longer lag while the remaining ones grew up their numbers.   For now, it's fermenting, and everything may be fine.   I'd wait and see.  Only if the fermentation stalls, or underattenuates,  you might want to consider pitching some more yeast -- preferably a starter at high kräusen -- to finish the job.  RDWHAHB.

It sounds like the remaining viable yeast may be very strained and, like Robert pointed out, the numbers were no doubt low.  The result maybe an ester bomb.  My suggestion is to let the fermentation go as far as it will, then take a reading and taste the brew.  From their you can decide what to do.  Meantime, you’re in it for the long haul.  So sit back and relax.
